    Subject[PATCH 5.15 070/171] cifs: Fix crash on unload of cifs_arc4.ko
    Date
    From: Vincent Whitchurch <vincent.whitchurch@axis.com>

    commit 51a08bdeca27988a17c87b87d8e64ffecbd2a172 upstream.

    The exit function is wrongly placed in the __init section and this leads
    to a crash when the module is unloaded. Just remove both the init and
    exit functions since this module does not need them.

    Fixes: 71c02863246167b3d ("cifs: fork arc4 and create a separate module...")
